Title: Method and device for observing logical circuit
Inventor: MIURA KAZUYA
IPC: G01R31/28
Filed: 2000-06-15
Abstract: PROBLEM TO BE SOLVED: To set the number of observation points separately from the number of set points for correction input signal while evaluation debugging continues for a logical circuit even if failure occurs at a plurality of observation points. SOLUTION: An m-ary address counter 12 outputs an SEL8 with a counter value as a selection signal 27. The SEL8 selects and outputs as an observation output signal 28, using a selection signal 27 out of observation signals (a normal output signal 24) acquired from an observation point in a logical circuit which is to be observed. If the observation output signal 28 is abnormal, a correction input signal 25 is applied from outside of the logical circuit for changing the logic of the signal. At an address decoder 9, a specification signal 26 (a counter value which is outputted to the address decoder 9 by an n-ary address counter 11) for specifying a selector for a point which requires change of signal logic is received, and an address corresponding to the signal is generated and outputted to selectors 5-7. The selector of the address selects the correction input signal 25.

Title: Method for compressing dynamic image information and its system
Inventor: KAJIKI NORIKO
IPC: H04N19/13
Filed: 2000-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for compressing dynamic image information capable of rapidly conducting a compressing process of data capable of predictively coding image information in high compressibility and its system. SOLUTION: The method for compressing the dynamic image information comprises the steps of comparing pixels handled as one block of 2×2 pixels between frames with each other, storing a part in which an absolute value of their difference is larger than a given parameter and a part except the previous part in a 1-bit bit map, processing (deleting) a part in which the absolute value of their difference is not larger than the parameter as a pixel not having a change between the frames, and processing to compress information of the part in which the absolute value is larger than the parameter. In this method, information of the presence or absence of the difference in the frame is bit map information corresponding to the 2×2 block in the frame.  The presence or absence of the difference between the frames is obtained by comparing a square mean error of (three) input data of an encoder, √  (A-A ')(A-A')+(B-B')(B-B')+(C-C')(C-C')} with the parameter. If the 'difference is present' is decided, the corresponding bit is stood as this is difference information in the frame.
